EV vs Gas Cost Per Mile in Utah
At Utah's average prices, a Tesla Model 3 RWD costs an estimated $0.033 a mile to charge at home and a 30 mpg gas car $0.113 a mile in fuel: $960.70 a year apart over 12,000 miles. Per mile, the EV spends about 29% of what the gas car does, the lowest band (35% or less) on this site.

Measured against its housing stock, Utah is one of the stronger EV markets: 6.6 battery-electric vehicles per hundred homes ranks the 6th-highest, and the nationwide ratio is 4.6. Measured against its vehicles, it ranks the 11th-highest: the 68,400 EVs registered at the end of 2025 are 2.3% of 2,923,500 light-duty vehicles, with the US at 2.1%. Another 19,200 plug-in hybrids take the share with a plug to 3.0%.
Charging here looks a lot like the national network. The 3,235 public ports at 1,028 locations include 1,041 DC fast and 2,190 Level 2, a fast share of 32% next to 30% for the country. For each port there are 21.1 registered EVs, and 66 for each fast port, figures that sit beside the national 21.7 and 72. So a Utah owner competes for a plug about as much as a typical American one; which stations fill up, and where the gaps are on the map, lies outside these counts.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in Utah
At 13.3¢/kWh, a Model 3 RWD (25 kWh per 100 miles, EPA) draws 25 kWh from the wall for every 100 miles (the EPA measures it at the wall), so each mile costs $0.033. A 30 mpg car at $3.40/gal spends $0.113 a mile. Over 12,000 miles: $399.30 for the EV, $1,360.00 for gasoline, a difference of $960.70 a year (fuel only). Per mile, the EV spends about 29% of the gas car's fuel cost.
What the numbers say
What the numbers say in Utah
The EV's fuel edge in Utah ranks the 5th-highest among the states for the page's example, and both prices push the same direction. Household electricity costs 13.3¢/kWh, the 3rd-lowest residential rate and 27% below the US average of 18.2¢/kWh, while gasoline averages $3.40/gal, the 9th-highest and 6% above the US average of $3.20/gal. Plugged in at home, the Tesla Model 3 RWD costs $0.033 per mile; on the US average rate it would cost $0.045.
To erase that edge, electricity would need to reach 45.3¢/kWh, compared with the 13.3¢/kWh average, or a gasoline car would need 102 mpg. That distance is room for public charging: a DC fast session priced well over the home rate still leaves the EV cheaper per mile while it stays below 45.3¢/kWh. Put a station's posted price into the electricity field to test it.
Utah's winter runs colder than the US norm, 5,700 heating degree-days or 27% more than the US average of 4,500, and cold lifts consumption above the rated figure behind this estimate for part of the year. The cold-weather range page sizes the effect; at 13.3¢/kWh, even the higher winter draw keeps the per-mile cost low.
Pickup drivers can read the Ford F-150 Lightning at the average rate: $0.064 per mile, compared with $0.033 for the car. Its fair opponent is the gas truck you would otherwise buy, with that truck's own mpg.
Check whether your utility bills by time of use; an off-peak price would replace 13.3¢/kWh in the calculator. Plug-in hybrid vs EV vs gas folds in the purchase price, and Level 2 installation cost covers the charger. On the heating side, cheap power meets cheap gas: see the Utah heating comparison.
Questions
FAQ
Is charging an EV cheaper than gas in Utah?
At Utah's average prices, yes for the page's example: $0.033 a mile for a Model 3 RWD at home against $0.113 for a 30 mpg car, $960.70 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 45.3¢/kWh, or against a gas car rated above 102 mpg. Both prices are editable above.
What about public fast charging in Utah?
Fast chargers usually charge more per kWh than a home rate. This page uses Utah's home average, 13.3¢/kWh. To see the cost per mile on the road, type the charger's price per kWh into the electricity rate field; the gas side stays at $3.40/gal.
How do time-of-use rates change this in Utah?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 13.3¢/kWh (6.7¢/kWh), the Model 3 RWD would cost $0.017 a mile instead of $0.033. Check your utility's tariff for the real overnight rate and type it in.
Is home charging in Utah cheaper than in most states?
The rate says so: 13.3¢/kWh is the 3rd-lowest residential price in the country. At that price the Tesla Model 3 RWD costs $0.033 per mile and $399.30 over 12,000 miles, while a driver on the US average rate would pay $0.045 per mile for the same car. If your utility offers an off-peak rate, type it into the calculator above for a figure closer to your own.
Does Utah have enough fast chargers for its EVs?
On the ratio, roughly in step with the country: 66 registered EVs for each DC fast port, with the national figure at 72, and 21.1 per port of any type, next to 21.7. Its 1,041 fast ports rank the 23rd-highest by count. Totals don't show placement, so before a long drive look up the stations on your route and what they charge per kilowatt-hour.
